These bottom Y members Yare; providedwth nuts? 25'V andV 26 Which/*are threaded; upon ythe reversely fthreaded; portion Vof the' screw21 so that -they Willjsimultaneouslyr approach or recede from each other upon rotation ofthe hand iwheel 2 2.; Hjdesired, acentrally located supporting member 27.1nay. be o sitioned belowathe overlapping portions23- and 2 4 of the bottom, ,and may ,thnsfsnpport in argid v manner, lsuch overlapping;l portions. The members 23 and 24 are provided with upwardly extending ends 28 and 29 which pivotally carry the top flaps 30 and 3l, re-` spectively. This box is adapted to be opened up, as shown in Figure 3, and to receive t-he springs encased in padding or similar material. Villen the box has received its charge,lthe iiaps 30 and 31 otthe top are rocked-:downwardly into overlapping ,position. In order to prevent these top members from movingY upwardly when the Vlilling;v is compacted, a relatively heavy bar 32 is adapted to be swung downwardly, as shown in Figurev 1, and to reinforce the overlapping portions of the flaps 30 and 31 of the top. 'i4-convenient way of arranging this upper reinforcing` strap or bar is` to pivot it between lugs of a bracket 33 supported from the bedplate. A latch 34 is pivotally carried by the bar 32, and is spring' pressed towards its inner position, as illustrated in Figure 1. This latch is adapted to hook beneath a portion of the bracket 33, as shown inFigure 1, to retain the bar 32 in its operative position. A

It will be seen that when the operator desires to manipulate the bar 32, he may do so through the medium of the latch handle 35, thus unlatchingr the bar and rocking it to inoperative position. "l/ihen the "lilling' has been placed within the bor', the llaps 30 and 31 of the box are rocked downwardly and, thereafter, the bar 32 is rocked into operati-ve position, as shown inFignre 1. The hand'wheel 22 is then ro tated to VforceV the sides or ends 28 or 29 towards each other the desired extent and to thus com )act the filling` as required. Thereafter, the open ended cover 36, as

.shown in ydotted lines vin Figure 1,'may be l slipped over the outwardly extending' filled bex, and the mechanism manipulated to project Vthe phmg'er 11 outwardly thus ejecting' the lilling and 'forcing it into the cover 3G in a uniform, even and lirm manner.

The mechanism for operating' the plunger is such that the operator is called upon merely to initiate the outward motion of the plunger. The mechanism automatically retracts the plunger and, thereafter, stops the machine ready for another cycle of operation.

This mechanism may comprise a pair ot intermeshing pinions 37 and 38 carried by the' outer arms of a triangular rock member 39, such member being provided with adjustable stops 39 and with a downwardly extending lug 40 to which a separate arm 41 is rigidly attached. These pinions are adapted to selectively engage the rack 4 and as -theyrotate in opposed directions, to im- 'part reverse reciprocatory motion to the rack 4, the pinion SSserving to project the plunger, and the pinion 37 serving to retract the plunger. The lower end of' the arm 41 is connected by means of a link 42 with an upwardly extending arm 43 of a foot' pedal '44 although, obviously, a hand operated device might replace the foot pedal. The lower end of the control arm 41 is further connected by means of a link 45 with the lower end of a lever 46, such lever being pivoted intermediate its ends, as indicated at 47.- `The upper end oi the lever 46 passes through a slot 48 in the bed plate2 and is arranged in lproximity to one side of the rack 4. The rack4 is Vprovided with a J1orwardly located pin 49 and with a rearwardly located pin 50, as may be seen from Figures 1 and 2.v These pins are adapted to engage the upper end of the lever 46 at the extreme portions of the stroke ofthe rack 4 andto thus rock the lever and shift the oscillatory i member 39, thus controlling the operation oi the plunger. A quick motion device is enr ployed for aiding.;` in rocking the oscillatory member S9l into plunger retracting position. This mechanism may comprise a tubular member 51 pivoted to the hip; 49 et the oscillatery member. This tubular member 51 slidably receives a rod 52, the Vlower endv of such rod being pivotall-y carried by the pin- Vtle pin 53 of. a bracket 54. This bracket is adjustably carried by a` stationary portion 55 ofthe machine, such stationary portion being' provided with an V`elongated slot through Vwhich a clampingfbolt 56 extends, as shown `in Figure Vthe position et the bracket 54, therac-tion ot' the quick motion mechanism may be initially controlled, Lock nuts 5? are threaded upon the lower end of the rodv 52 and adjustably j compress a helical spring 58 loosely surrounding vsuch rod, the upper end of the springbearing against the lower end oit the tubular member 51.

provided with an outer pulley 64, although,

obviously, a motor maybe employed in place of 'the drivingpulley 64.

The operation of the'apparatus is as -iollows The box is thrown into open Yposition, as shown in'fFigure 3, and the lilling,

such as box springs surrounded loosely byv batting is 4placed within the'box. Thereafter, the covers 30 4and 31 are swung downwardly and bar 32 is swung into locked position. The exactwidth fer-the box is attained by adjusting the hand wheel v22, as

previously described;` The operator then intarieven and uniform manner positively po-Y e sitionmg 1t within the casing 36. As the` l0 sertsthelopen endedcasing` for the cushav ion' over the filledfboxVK v Thereafter, he depresses the'pedal 44, thus rocking. theioscillatorymember 39 in a clockwise directionV and causing the pinion 38 thereof to engage the rack.4.` Thisvl projects the plunger 1l'l Yforwardly andfejects the 4filling material in plungerrack 4 travels forwardly, the rearmost pin- 5() engages the upperlend of the,

lever 46 andV rocks the Y roscillatory member 39 in a counterclockwise direction, such mo# tion being aided by theY quick motion mechanismV described. This places the retracting pinion"37 in engagement withthe plunger. rack 4 and the plungerfis thusV automatically retracted. When the plunger arrives at its rearmost position, the pin 49 rocks thelevery 46 and through the link mechanism rocks Vthe oscillatory member 39 in a counterclock-y wise direction. 'However, the rset` of the y quick motion mechanism is such-that ltheos.
